Title: Flexible cable actuator for vehicle heater - has cable wound on drum in cylindrical housing to conserve space
Inventor: MEYER ERNST DIPL ING
IPC: G05G1/02
Filed: 1974-02-05
Abstract: The cable housing is provided with a centre journal on which a cylindrical disc is able to turn. The disc carries the flexible pull and push element whose one end terminates as a nipple to which the pull wire is hooked. The turning movement of the cylindrical disc is limited by the cam which strikes against the projection at the beginning and end of its travel. A cover plate has an engaging piece which turns the disc and also serves as a fitting for a display lamp. The pull cable outer cover is led to the housing by a pull stop tube.

Title: Petrochemical effluent disposal - by heat exchange, stripping and evaporation below atmospheric pressure
Inventor: LINDE ROBERT VON DIPL ING
IPC: C02F1/04
Filed: 1974-03-01
Abstract: The hot and pressurized effluents of petrochemical plants contg. soot and ash in addn. to gases are treated by first recovering the greater part of their heat content in a heat exchanger before they are allowed to expand. This heat is used to evaporate a part of the expanded wash water. A stripper removes the gaseous components. Screening of decanting can be applied to eliminate the solid components. This process has much lower operating costs than thermal disposal of the pollutants. The vapours are emitted into the atmos. without odorous of toxic admixts.

Title: Relief printing plate has etched metal surface - on plastics, esp. polyester, backing to give dimensional stability
Inventor: BLUNDELL JOHN MARK
IPC: B41N1/06
Filed: 1974-07-12
Abstract: A printing plate comprises laminated material, consists of a supporting layer of electrically insulating plastics and a facing layer of etched metal. The supporting layer is of a material which is chemically resistant to the etching agent and possesses high bending strength and dimensional stability; the metal surface is suitable for relief printing and the binding agent between the metal surface and the backing layer possesses high shearing strength; the reverse side of the supporting layer is faced with an electrical resistant heating element, e.g. of meandering shape, and the supporting layer is sufficiently thin to provide effective heat transfer between the heating element and the metal surface. Pref. the heating element is connected to a switch unit regulated by electrical signals received from sensors, which respond to the pressure and/or temp. during pressing. Both the metal printing surface layer and the heating element may be formed by etching, esp. using the supporting layer as the sepg. panel where two different etching processes are used. Used esp. for relief printing, to provide a more economical method of making the plate.

Title: Connected lateral fuel tanks - with float valve to seal fuel intake chamber to prevent air intake
Inventor: FORSTNER EGON
IPC: F02M37/00
Filed: 1974-09-03
Abstract: The fuel tanks for the low profile vehicle arranged to straddle the exhaust pipes (6, 7) and transmission (5) with the lateral tanks (4, 8) connected by a large diameter pipe (10) set some distance above the bottoms of the tanks. Fuel collection chambers (11, 12) are set under each tank with the two collection chambers connected by a siphon pipe (13) mounted through the larger diameter connecting pipe. One of the tanks has a fuel intake pipe (18) with its filter protected intake (19) mounted in the collecting chamber. The chamber is separated from the rest of the tank by a float operated valve (24). As the fuel level drops to the height of the valve it closes so that the fuel suction draws fuel from the bottom of the other tank via the siphon pipe.
Patent DE-2444348-A1 (DE)
Title: Gas removal from scraper conveyor bottoms - has main duct with choke effecting venting sleeves at intervals
Inventor: HOELTER HEINZ
IPC: E21F7/00
Filed: 1974-09-17
Abstract: Removal of gas from bottom strands of scraper chain conveyors in the mining sector is effected by a combination of a flexible main infeed duct fitted out with ventilating sleeves at appropriate intervals. The diameter of the sleeves produces a choking effect depending on the fall in pressure within the main duct and in this way ensures that issuing air cannot whirl up the dust arising during mining operations. The sleeves increase in dia., starting from the input point towards the centre of the face. This ensures that ventilation remains constant right the way along the conveyor. The venting effect successfully clears gas build-ups from the bottom strand and so prevents ignitions caused by friction between chains and flights.
Patent DE-2454436-A1 (DE)
Title: Hydraulically operated cable cutting and crimping tool - with spring return of operating piston to open position is of small dimensions
Inventor: MATTERA JOHN A
IPC: H02G1/00
Filed: 1974-11-16
Abstract: The object is to produce a small cable cutter and crimper which can be used in confined spaces. It comprises a barrel (20) containing the operating piston (28) which is hollow and in turn contains a rod (32). The piston end can take the exchangeable dies which, under hydraulic pressure, bear against the anvil located (83) in the hooked outer end of the tool. The rod (32) is surrounded by a return spring (37) which acts to retract the piston to the open position when the hydraulic pressure is switched off. The free end of the tool has an opening (50) for the insertion of cables, and for access to the die and anvil. By exchanging the die for a knife the tool can be used to cut cables to length.

Title: Compressible-unit box-frame concrete wall interior formwork - with corner-covering membrane and clamp structure for close fitting and release
Inventor: MISCHEK HUGO DIPL ING
IPC: B28B7/22
Filed: 1975-03-26
Abstract: The sheathing, for interior wall concreting, without the need to dismantle or destroy it after the work is completed, comprises a box-type closed frame with shuttering walls in parts, which can be pressed inwards. It has a membrane continuing across the corners, and a clamping structure joined to this in an area away from the corners.

Title: Automatic foot released ski brake - has spring loaded slide to push rotating arm into snow
Inventor: BILDNER HEINZ
IPC: A63C7/10
Filed: 1975-12-23
Abstract: The ski-brake (1) is screwed to the ski through holes and a metal strip (7) slides in a guide and is normally held in position by the pressure of the skier's foot. Once the skier's foot is removed a spring inside the housing (2) pushes the strip (7) to the left and a toothed rack attached to the strip (7) rotates a pinion. The pinion is mounted on a transverse shaft which carries arms (8a) at each end. As the pinion rotates the arms (8a) move from the horizontal to the vertical position and dig into the snow. The arms thus act as a brake and bring the released ski rapidly to rest.
